- The exam is one four-hour, hands-on session in a working OpenStack cloud, not a multiple-choice test.
- Configurations you build must survive a reboot without manual intervention.
- Red Hat lists a standard USD 500 exam list price and a credential that stays current for 3 years.
What EX210 Actually Is
EX210 is the exam code for the Red Hat Certified Specialist in Cloud Infrastructure credential. It is issued by Red Hat, Inc. and tests whether you can administer a Red Hat OpenStack Platform cloud: the kind of day-two work that cloud operators perform after the platform has been installed. Candidates are asked to complete real administrative tasks on live systems, and the results are checked against objective outcomes.
If you have seen "EX210" attached to other credentials elsewhere, set those aside. On this site the code refers only to the Red Hat exam described here. For a shorter orientation to the acronym itself, see our explainers on what EX210 is and what EX210 stands for.
The Name Change: RHCSA in OpenStack vs. Specialist in Cloud Infrastructure
Many candidates trip over naming. Red Hat's current exam and credential pages use "Red Hat Certified Specialist in Cloud Infrastructure." However, legacy URLs and some older text still refer to the credential as "Red Hat Certified System Administrator in Red Hat OpenStack." These are the same exam code and the same credential family; the wording simply changed over time.
Practically, this means you may find older blog posts, course descriptions or job listings using the earlier name. When you check requirements or book the exam, rely on the current Red Hat pages and the EX210 code rather than the title alone.
How the Exam Works: Four Hours in a Live Cloud
The format is the heart of what makes EX210 distinctive. You sit a single section lasting 4 hours, working inside a running Red Hat OpenStack Platform environment. You are given tasks to accomplish, and your result is determined by whether the resulting configuration meets the stated requirements.
| Attribute | EX210 |
|---|---|
| Issuer | Red Hat, Inc. |
| Style | Hands-on performance tasks in a live Red Hat OpenStack Platform cloud |
| Duration | One section, 4 hours |
| Question count | Not publicly specified |
| Passing score | Not verified in current official pages |
| Delivery | Red Hat's own proctored individual, remote and classroom delivery, subject to booking availability |
| Validity | 3 years |
Be wary of third-party claims that describe EX210 as a 60-question or 90-minute multiple-choice test. That does not match Red Hat's description of a four-hour practical exam. We cover the scoring question in more depth in our passing score guide.
Rules of the room
Outside assistance is prohibited under Red Hat's general handbook. The exam page does not publish an exact inventory of the product documentation supplied, so do not plan around a particular reference being available; learn to find answers quickly using the built-in help and tooling you would rely on in daily work. Remote testing requires compatible equipment and live proctoring where booked.
The Ten Objective Areas
Red Hat's current page lists ten top-level exam-objective headings. These are objective areas rather than a course syllabus, and Red Hat does not publish percentage weights, so no one can honestly tell you which area is "worth the most." Treat all ten as testable. A fuller breakdown lives in our guide to all 10 EX210 content areas.
Domain 1: Manage the Red Hat OpenStack Platform control plane
The control plane is the brain of the cloud. Expect to work with the services that run the platform and keep them healthy.
- Understand how core services relate to one another
- Know how to inspect and manage service state
Domain 2: Manage infrastructure security
Covers protecting the platform itself rather than individual users.
- Secure the services and communication between components
- Apply controls that persist across restarts
Domain 3: Manage user security
Focuses on who can do what inside the cloud.
- Work with identities, projects, roles and access
- Understand how permissions shape what a user can launch or modify
Domain 4: Manage application deployment resources
The resources workloads depend on before and during deployment.
- Prepare images, flavors and related resources
- Understand how deployment resources feed instance creation
Domain 5: Manage storage in Red Hat OpenStack Platform
Storage for instances and applications.
- Provision and attach storage to workloads
- Understand the different storage services and their purposes
Domain 6: Manage networking
Connecting instances to each other and to the outside world.
- Build and verify virtual network topologies
- Diagnose connectivity from the instance outward
Domain 7: Manage compute node operations
The hosts that actually run instances.
- Understand how compute capacity is added, maintained and scheduled
- Be comfortable with operations that affect running workloads
Domain 8: Monitor operations
Seeing what the cloud is doing.
- Use available telemetry and logging to understand platform health
- Interpret what you observe, not merely collect it
Domain 9: Automate cloud application deployment
Moving from one-off commands to repeatable deployment.
- Use orchestration approaches to stand up applications consistently
- Read and adjust templates under time pressure
Domain 10: Troubleshoot operations
Finding and fixing what is broken.
- Work methodically from symptom to cause across services
- Combine knowledge from every other domain
Key Takeaway
Domain 10 is where all the others collide. A broken instance may be a networking, storage, security or control-plane problem. Practice diagnosing across boundaries instead of studying each service in isolation.
Who Should Sit the Exam
EX210 suits administrators who already operate, or are about to operate, a Red Hat OpenStack Platform cloud. Typical profiles include:
- Linux system administrators moving from managing individual servers to managing cloud infrastructure
- Cloud operators who want documented proof of hands-on OpenStack capability
- Infrastructure engineers at organizations that run Red Hat's private cloud stack
- Consultants and integrators who deploy or support Red Hat OpenStack Platform for clients
It is less obviously suited to someone who has never touched a Linux command line or who works exclusively with public-cloud services. Our difficulty guide discusses how the practical format feels to people from different backgrounds.
Prerequisites and Recommended Background
Red Hat's page recommends the following preparation:
- RHCSA or comparable work experience and skills
- CL110 and CL210, or comparable Red Hat OpenStack Platform experience
- A careful review of the published exam objectives
Importantly, the exam page explicitly says course attendance is not required. There is no mandatory degree, fixed number of experience hours, training hours or reference count published. In other words, the barrier is capability rather than paperwork. For a closer look, read our EX210 requirements guide and our overview of EX210 training options.
Booking, Fees and Retakes
Red Hat delivers its own proctored exams in individual, remote and classroom formats, subject to what is actually available for EX210 at the time you book. It is not a verified Pearson VUE or PSI appointment, so do not look for EX210 on those platforms.
| Item | What Red Hat states |
|---|---|
| Standard list price | USD 500 for Red Hat certification exams |
| Regional pricing | May vary; confirm the amount at checkout |
| Member discount | No member/non-member differential is published |
| Retake | Available after an unsuccessful first attempt; the program guide describes one free second attempt for an initially purchased paid exam |
Reseller discounts you may see advertised are not Red Hat's own exam fee. Because the exact EX210 checkout amount can differ from the general list price, treat USD 500 as the standard reference point and verify at purchase. See our cost breakdown and exam dates guide for planning your schedule and budget.
Results, Validity and Renewal
When results arrive
Red Hat's sources are slightly inconsistent here. The EX210 page says results are usually available within 3 US business days and reported as total scores, while the general program guide says within 5 business days with objective-area feedback. Neither offers individual exam-item feedback, so plan for a short wait without assuming an exact turnaround.
How long it lasts
The credential is current for 3 years. A May 2026 Red Hat framework and FAQ describe renewal through retaking the highest-level exam, adding a certification at the same level, or advancing to a higher level, with applicable specialization and transcript rules still mattering. The program guide also supports simply retaking the original exam to renew. An older standalone page describes Specialists as renewing only by retaking their own exams. Where they conflict, the newer framework is the better guide, and retaking EX210 remains the most commonly verified route. Renew before your status lapses.
No EX210-specific continuing-education quota or CEU-only renewal route is published, and rules written for other Red Hat credentials do not automatically apply.
Where the Credential Fits in a Career
EX210 signals practical competence with Red Hat's private-cloud platform, which matters most to employers who run or support that stack: enterprises operating private clouds, service providers, and integrators. Roles that commonly benefit include cloud operator, infrastructure engineer, platform administrator and systems administrator with cloud responsibilities. See EX210 jobs for the kinds of roles to target.
We deliberately avoid quoting salary numbers here because Red Hat publishes none for this credential and we will not invent them. For an honest framing of earnings and return on investment, read our salary guide and our analysis of whether EX210 is worth it. Likewise, no independent credential-wide pass-rate dataset was located; our pass rate article explains what is and is not known.
Sequencing Your Preparation by Domain
Because Red Hat publishes no weights, spread your effort across all ten areas, but order them so each builds on the last. One reasonable sequence:
Foundations of the platform
- Control plane services (Domain 1)
- Infrastructure and user security (Domains 2 and 3), because later tasks assume you can authenticate and authorize correctly
Building blocks for workloads
- Deployment resources (Domain 4)
- Storage (Domain 5) and networking (Domain 6), the two areas instances depend on most
Operations and repeatability
- Compute node operations (Domain 7)
- Monitoring (Domain 8) and automation (Domain 9)
Integration under the clock
- Troubleshooting (Domain 10) across everything above
- Timed, four-hour practice runs with reboot-persistence checks
For a fuller plan, see the EX210 study guide and keep the cheat sheet nearby for quick review. When you want realistic exam-style repetition, return to our practice tests.
